"It is still a long way from this morbid isolation, from the desert of these experimental years, to that enormous, overflowing certainty and health which cannot do without even illness itself, as an instrument and fishhook of knowledge; to that mature freedom of the spirit which is fully as much self-mastery and discipline of the heart, and which permits paths to many opposing ways of thought. It is a long way to inner spaciousness and cosseting of a superabundance which precludes the danger and the sprit might lose itself on its own paths and fall in love and stay put, intoxicated, in some nook; a long way to that excess of vivid healing, reproducing, reviving power, the very sign of great health, an excess that gives free spirit the dangerous privilege of being permitted to live experimentally."
